WASH-BOARD.

SPECIFICATION forming part of Letters Patent No. 360,384, dated March 29. 1887.

Application lilcd June 22, 1886. Serial No. 205,867. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD GROVE, a citizen of the United States, residing at North Lima, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Wire I'Vash-Boards,ofwhicl1 the following is a specification.

This invention relates to an improved washboard, and is illustrated in the accompanying drawings, in whichl Figure l is a view of the improved washboard. Fig. 2 is a longitudinal section of the wash-board on line down the center, omitting the wires. Fig. 3 is a cross-section ofthe washboard taken on the line y through the center, omitting the wires. Fig. 4 is a view of the back board detached. Figs. 5, 6, and 7 show the diiferent forms of twisted and braided wire that may be used in the manufacture of this 2o wash-board.

4o may be used for thispurpose.

The rubbingsurface of this wash-board consists of twisted, braided, woven, or crimped wire.

The letter A designates the side bars, and B the board or back. The side bars, A, are connected by the top strip, c, and two crossbars, d, the ends of which latter are mortised into the side bars. The back board, B, is secured to place by its side edges, e, entered in grooves c', cnt in the side bars and thetop and bottom edge, each having` a groove,f, which takes on the crossbar d. It' desired, nails may be driven through the side bars, A, and cross-bars d into the edges of the back board.

The twisted, braided, woven, or crimped wire g is secured to the back board in the form of oval or circular coils. Any convenient or suitable means may be employed for securing the wire tothe back-board. Staples 7L For staying the several coils,so as to keep the spaces t' between them of uniform width, a wire crimped or bent to form upward-projecting shoulders may be used, like that designated d in my United States Patent No. 216,181, of June 3, 1879; or, instead of such stay-wire, a metal strip suitably notched on one edge may be used like that designated 7i in my said patent. If desired, the wires g of the rubbingsurface may be soldered to said stay wire or strip. The wires comprising the rubbingsurface when coiled in this way on a level-surfaced board afford the advantage of present ing to the clothes, when grasped by the hand and rubbed up and down, a constantly-changing surface.

The wires comprising the rubbing-surface may be coiled on a back board, having a con- Vex surfaceJc, as shown in the drawings. This back board on one surface is raised at the center, or slightly slopes from the center in all directions toward the edges. It is thus thickest at the center, and produces what is here termed the "conveX surface.77 A wash-board made of wires and having this feat-ure is found to be more effective.

The wires g of the rubbing-surface may be constructed in a variety of ways,of which eX- amples are shown in Figs. 5, 6, and 7. In Fig. 5 two wires, g, are twisted together. In Fig. 6 one flat wire, g, is twisted or spiraled; and in Fig. 7 three wires, g, are twisted together. y

The wires may be made of copper, iron, or steel, and galvanized or tinned to prevent oxidation.

Having described my invention, I claim and desire to secure by Letters Patent ofthe United Statesl. A washboard having a back, B, and a rubbing-surface consisting of wires secured to the said back in the form of oval or circular coils, as set forth. 2. A wash-board having a back with a con- Vex face, 7c, and wires coiled upon and secured to said convex face, as set forth.

' In testimony whereof I afx my signature in the presence of two witnesses.
